when clothes have stains, bleach may be added to the wash to react with the soil and make the stains colorless. the bleach solution is prepared by bubbling chlorine gas into a solution of sodium hydroxide to produce a soultion of sodium hypochlorite, sodium chloide and water. one brand of bleach contains 5.25% sodium hypochlorite by mass with a density of 1.08 g/ml. a) what is the formular and molar mass of sodium hypochlorite? b) draw the lewis structure for...

In the Iodination of Salicylamide, active iodine was created by the action of sodium hypochlorite on sodium iodide. When the reaction was complete, 10% sodium thiosulfate solution was added to the reaction mixture before acidification. What is the role of sodium thiosulfate in this procedure? A. It tests the pH of the mixture. B. It destroys excess sodium hypochlorite. C. It removes water from the organic layer. D. It protects salicylamide from the harsh acid. I have seen that the...

During lab you measured the pH of mixtures containing strong acid and strong base. Write net Brønsted equations that show the acid-base reactions of common household items. For polyprotic species (such as vitamin C, lemon juice, and washing soda), please show only one proton transfer. Remember that spectator ions are not included. (Use the lowest possible coefficients. Omit states-of-matter in your answer.) (a) bleach and vinegar (sodium hypochlorite and HC2H3O2) (b) bleach and Vitamin C (sodium hypochlorite and H2C6H6O6)

The salt sodium formate, NaCHO2(s), completely dissociates into Na+(aq) and CHO2−(aq) in an aqueous environment. The Na+ ion has no acid or base properties, but the formate ion is the conjugate base of the weak acid, formic acid. Part a. Write a balanced chemical equation showing how the formate ion reacts with water to affect the pH of the resulting solution (you can ignore the sodium ion in your balanced equation). Part b. Find the pH of a 0.100 M...

A calorimetry investigation is performed to determine the heat of neutralization when hydrochloric acid and sodium hydroxide solutions are mixed. Write the complete chemical equation for the reaction between hydrochloric acid and sodium hydroxide. Write the net ionic equation for the reaction between hydrochloric acid and sodium hydroxide. The procedure then calls for measuring 50.00 mL of each 0.10 molar solution. Why is it important to measure the volumes as accurately as possible? What is the most accurate measuring instrument...
